I have a Yamaha CD-R/RW deibe in a Windows XP system. It was working fine until now. Suddebly it stops working. It has lights on. In the device manager, it shows active and XP support also shows it is active. But it doesn’t play or record any CD. When I try to burn Cd, the message says that “please put a blank cd” although there is a blank CD in the drive.
